Episode Summary: Gaius is a powerful sorcerer, but his power has reached the limits of what the crest on his hand is able to accommodate. In order to hopefully gain the benefits of an additional fourth mark, he chooses to roll the dice and reincarnate into a new body. He’s reborn as Matthias, son of Castor, and he now bears his desired crest. The only issue is that, between his death and his current life, the world has changed quite a bit. His treasured crest is thought of as weak, and spellcasting is almost exclusively performed with incantations rather than quickly and without speaking (as Gaius/Matthias had been taught).
Matthias meets two friends, Alma and Lurie, who are preparing to take the entrance exam for a magic academy. Curiosity inspires Matthias to join them, and his incantation-less spellcasting draws the attention of the school headmaster. While their main campus has long since abandoned this type of magic, the headmaster at the secondary campus is interested in bringing it back as a skill – the only problem being that there’s no one around to teach it anymore. Enter Matthias, who’s recruited to do the job. A month later, when the two campuses are set to compete in a magic tournament, Matthias uncovers the fact that demons have infiltrated the main campus and poisoned the curriculum against teaching the type of magic that might allow human beings to defeat them.
